ZoneDefender
80kA power surge protection for small distribution panels,
tower lights, equipment cabinets and confined spaces
AC or DC application
Straightforward and simple installation -- wall
or flush mounting
LED status indication via solid state
diagnostics plus remote indication contacts
Thermal and short circuit fusing
UL 1449 2nd Edition Listed
10 year product warranty
The ZoneDefender Series of power surge
protection devices has been specifically
designed for interior lighting and small
distribution panels. These compact and
durable devices offer cost effective, high
capacity protection along with application
versatility, features which make the Series
the ultimate surge protection solution.
ZoneDefender units, with a 80kA surge
handling capability per phase, provide
protection between Line to Neutral, Line to
Ground, Line to Line and Neutral to Ground.
Utilizing Metal Oxide Varistor (MOV)
technology, the ZoneDefender’s protection
circuits are highly reliable, dual-redundant
varistor networks ensuring your site is never
unprotected. Fully automatic in operation,
ZoneDefender reacts immediately, clamping
voltage surges without causing undue
leakage losses under normal operation. No
operator
intervention
is
required,
ZoneDefender resets automatically and is
maintenance free.
Suitable for AC or DC applications,
ZoneDefender devices provide protection for
AC or DC power supplies with no restriction
to the amount of load current. ZoneDefender
DC versions are available utilizing SAD
(Silicon Avalanche Diode) technology in
addition to the standard MOVs. DC versions
are also available with EMI filtering, should
this be required.
Thermal fusing is incorporated into each
ZoneDefender as an additional safety feature.
Short circuit protection is also supplied, as
standard, for added peace of mind.
Installation is simple - the NEMA 4X
enclosure of ZoneDefender devices can be
easily ‘wall mounted’. Alternatively,
ZoneDefender units may be flush mounted by
way of an optional mounting plate which
should be specified at time of order
placement.
The ZoneDefender Series is UL 1449 2nd
Edition Listed and boasts an unrivalled 10
year ‘no questions asked’ manufacturers
product warranty. Zone-Defender devices
also exceed the requirements of
ANSI/IEEE C62.45 and
ANSI/IEEE C62.41.
ZoneDefender offers an LED Status
indication facility allowing each varistor
network to be continually monitored and
indicated by LEDs on the front panel of
the device. In addition, remote
monitoring is enabled by the
units’
remote
indication
contacts.
